The Hioki IR405310 is a digital insulation resistance tester for photovoltaic generation systems. Measure insulation resistance accurately and safely without being affected by generated solar power and identify the value in just 4 seconds.
Measurement not affected by generating PV
The IR4053-10, which was designed for PV, can accurately measure insulation resistance without being affected by the generating PV.
Displays measurement in 4 seconds
The IR4053 displays the measured value just 4 seconds after starting measurement. After the first display, the displayed value is updated each second. Comfortably carry out swift measurements.
Turn off the Isolator
Check the open voltage and polarity
Measure between P (+) and the Earth
Measure between N (-) and the earth
If there is no problem in the measurement between the earth and p (+) the IR4053-10 continues on to measure the insulation resistance between N (-) and the earth. When the voltage is detected, the IR4053 will inform you of earth fault with a red flash.
Measure with PVΩ function
Use the PVΩ function to accurately measure the insulation resistance. Because it is a PV dedicated function, you can get accurate values that is impossible with normal insulation resistance measurement.
